How long will dehydrated green beans keep?

At least a year. As long as you dehydrate the beans properly and store them in an airtight container in a cool, dry place, they should keep well. You could also use food storage bags to store your dehydrated vegetables. I use a food saver vaccum sealer machine for this.

Are dehydrated beans still healthy?

Yes, they are! Dehydrated food retains its nutritional content better than fresh produce. When you store fresh produce in the refrigerator, it begins to lose vitamins and minerals after only a few days.

Why should I blanch the beans?

You don't have to blanch the beans, but it keeps the color of the beans better, stops the enzymes from aging your beans, and locks in the flavor.

Can I dry string beans?

Yes! You can dry any type of green bean using these methods. If you are using string beans, you'll can reduce the drying time as they will be done sooner than the thicker style green beans.

Instructions

Wash your green beans and remove any soil from them.
Trim the ends by snapping them off by hand or using a kitchen knife or scissors to snip them. Cut the beans into 1-inch pieces.
Bring a large pot of water with a generous pinch of salt to a boil.
Fill a large mixing bowl with ice and cold water while you wait for the water to boil.
When the water begins to bubble, carefully place the beans in the water.
Boil for 3 minutes. Your beans should be bright green and crunchy.
Carefully pour the water and beans into a colander to drain the hot water. Then, transfer the blanched beans to the ice bath. Let them sit for at least 30 seconds to stop the cooking process.
Drain the beans after they’ve cooled.
Pat the beans dry to remove the excess water.
DEHYDRATOR INSTRUCTIONS: Carefully lay your green beans out onto the dehydrator sheets or a baking sheet in a single layer. Place the sheets into the dehydrator for 6 to 8 hours at 125°F.
OVEN INSTRUCTIONS: Preheat your oven to 125°F. Carefully lay your green beans out onto an oven sheet in a single layer. Place the sheet into the oven for 8 to 12 hours. Check the beans after 8 hours to see if they’re dry. The time it takes to dry will depend on the humidity levels.
Turn the dehydrator off and allow the beans to cool completely. If you are using an oven, remove them from the oven and let them cool.
Store your dried beans in a cool, dark environment in an airtight container.

Notes

Conventional ovens don’t maintain consistent temperatures at low settings, so cooking times vary from oven to oven. Keep checking on your beans from around 8 hours onward.
To rehydrate your green beans, soak them in hot water for an hour or cold water for two hours.
If you’re adding the dehydrated green beans to a casserole, stew, or soup, add a little extra water or stock to the recipe.
